Problems solved by technology

However, in this structure, in order to change the paper to be used, the user must first remove the two stacked paper feed cassettes from the main body of the image forming apparatus, turn the paper feed cassettes so that the vertical positions of these paper feed cassettes are aligned with each other. swap, then reinstall them on the main body
That is, as in the above-mentioned Japanese Patent Application Document No. HEI-11-599925, it is necessary to disassemble the paper feed cassette every time the paper to be used is to be changed, thereby complicating the image forming operation

Embodiment Construction

[0028] Image forming apparatuses according to aspects of the present invention will be described below with reference to these drawings, in which like parts and components are denoted by like reference numerals to avoid duplication of explanation.

[0029] First, an imaging apparatus 1 according to a first exemplary aspect of the present invention will be described with reference to FIGS. 1 to 8 .

[0030] An image forming apparatus 1 to which the present invention is applied is a multifunction device (MFD) having a printing function, a copying function, a scanning function, and a facsimile function. As shown in FIGS. 1 and 2, the image forming apparatus 1 includes a housing 2 made of synthetic resin injection molding. A first sheet feeding cassette 3 containing a stack of sheets P is provided in the bottom of the housing 2 . The first sheet feeding cassette 3 can be pulled out of the casing 2 through a discharge opening 2 a formed in one side of the casing 2 . Note that, in...

Abstract

A sheet feeder includes a first sheet feeding cassette capable of accommodating a stack of recording media, and a second sheet feeding cassette capable of accommodating a stack of recording media smaller than that contained in the first sheet feeding cassette. The second paper feeding cassette is provided on the first paper feeding cassette in a movable manner relative to the first paper feeding cassette. The second paper feeding cassette includes a first accommodating portion and a second accommodating portion. The second receiving portion is movable relative to the first receiving portion between a closed position and an open position. The second accommodating portion exposes the accommodating portion of the first sheet feeding cassette wider in the open position than in the closed position.

Description

[0001] This application claims priority from Japanese Patent Application No. 2005-286389 filed on September 30, 2005. The entire content of this priority application is hereby incorporated by reference. technical field [0002] The present invention relates to a sheet feeder capable of feeding recording media one sheet at a time from a first sheet feeding cassette and a second sheet feeding cassette capable of advancing and returning while accommodating the recording medium. It is set on the first paper feeder in the way of shrinking. The present invention also relates to an image forming apparatus including such a sheet feeder. Background technique [0003] Conventional image forming apparatuses such as various printers and facsimiles generally include a paper feed cassette containing a stack of paper or other recording media, and feed the paper one sheet at a time to a recording unit to form an image thereon. In order to form images on different types of paper, various p...
